Abstract

The paper deals with stepper motor control using microcontroller ATmega8-16PU. In the paper are mentioned two ways of control, namely full-step mode and half-step mode control. At first, bipolar stepper motor is introduced. For stepper motor control it has to be used H-bridge as well as amplifier in one module. Next, there is created measuring stand consisting of bipolar stepper motor SY28STH32-0674A with one step angle 1.8° and revolute encoder ISC3004 with 360 CPR. During the experiment were measured angular velocities by I/O measuring card MF624 cooperating with Matlab/Simulink. The results show differences between used two stepping modes of stepper motor.
